PUMP.

Application filed May l, 1919.

To all whom t may concern:

Be it known that GABE ELLiNGsoN, a citizen of the United States,residing at Kimball, in the county of Brule and State of South Dakota,have invented a new and useful Pump, of which the following is aspecification.

This invention relates to improvements in pumps, the object of theinvention being to provide an improved double pump, that is to say, apump formed of a pair of cylinders cast in one block side by side', andwhich pump is adapted to be driven by a worm gear and also by hand.

WV ith the foregoing and other objects in view, which will appear as thedescription proceeds, the invention consists of the novel features ofconstruction and combination of parts which will be fully describedhereinafter and particularly pointed out in thel claim.

ln the drawings accompanying and forming part of this specification,

Figure 1 is a sectional elevation of a pump constructed in accordancewith the present invention;

Fig. 2 is a side elevation illustrating in broken lines the applicationof a handle for manually operating the pump;

Fig. 3 is a cross section of the pump, taken on the line 3 8 of Fig. 1,looking in the direction of the arrows; and

Fig. l is a side elevation, partly in section of a handle adapted foruse in the manual operation of the pump.

The same characters of reference designate the same parts in thedifferent figures of the drawings,

Referring to the drawings, 2 designates a pair of cylinders cast in oneblock, and 3 a discharge chamber, preferably integral with the cylindersand provided with a single discharge port 4 adapted for connection to apipe or hose, each of the cylinders having a valve-controlled outletopening 1n communication with said discharge chamber. The cylinders 2are each provided with an inlet opening 5 adapted to be connected to acommon water supply pipe 5. T he inlet openings are in communicationwith the relatively large valve cylinders 6 and 7, each of which valvecylinders houses a spring member 8, which spring members restrict themovement of the ball valve mem- 65 bei-s 9, which ball valve members areheld Specification of Letters Patent.

to their seats, by means of the threaded plugs 10", operating in thethreaded ends of the valve cylinders 6 and 7. Each of the cylindersisprovided with a a piston rod 7, which passes upwardly through an openingin the cover 8 Vof the cylinder and is pivotally connected at the outerend thereof with a pitman 9. Mounted on the cylinders is a suitabletwo-part housing 10, 11, provided at opposite sides thereof withbearings 12 in which are journaled the ends of a shaft 13, said shafthaving secured thereto at each end thereof a crank 14, to which cranksthe ends of the pitmen 9 are pivotally connected. On the shaft 13 issecured for rotation therewith a worin wheel 15 adapted to mesh with aworin 16 journaled in the lower part of the housing 10 and provided atone end thereof with a pulley 18 by means of which power may be receivedfrom any convenient source.

For permitting the pump to be operated by hand, I have provided a handle19 that is bifurcated at its lower end and provided with openings 20adapted to fit the ends of the shaft 13, whereby, on removal of thecranks 14 from the ends of the shaft the ends of the handle may besubstituted therefor, the pitinen 9 being then pivoted at their upperends to the handle at 21. It will thus be seen that by the provision ofthis handle the pump may be used either as a power pump or as a handpump, by merely removingr the cranks 9 and substituting the handletherefor. The pump described is partcularly well adapted for use infilling threshei tanks, or for any other use where a continuous supplyof water is desired.

While l ha fe described in detail the structure herein illustrated, itis to be understood that I do not thereby limit my invention to theprecise features of construction shown, as I am aware that manymechanical changes may be made therein without departing from the spiritand'scope of the invention as set forth in the appended claim.

laying thus described my invention, what I claim is:

in 'a portable double acting pump, a casing, cylinders within thecasing, said casing having enlarged inta-ke openings formingvalvecylinders, in communication with the cylinders, intake ports disposed atan angle with relation to the cylinders and intake openings, springmembers supported within piston 6 secured to..

the valve cylinders, ball valves in the valve In testimony that I claimthe foregoing Cylinders and operating against the tension as my own, Ihave hereto affixed my signaof the spring members, means for regulatingture in the presence of two Witnesses. the movement of the valvemembers, exhaust Y GABE ELLINGSON.

5 ports disposed at an angle With relation to Witnesses:

the cylinders, pistons in the cylinders, and H. A. SGHOENBERGER, meansfor operating the pistons. FRED GRISWOLD.
